◍ prokaryotic cell.
Answer: cell that does not have a nucleus or other membrane-bound
, organelles.
◍ Eukaryotic cells.
Answer: Contain a nucleus and other organelles that are bound by
membranes.
◍ Carl Woese.
Answer: Devised a system of classification based on the cellular
organization of organisms (bacteria and archaea)
◍ Protista Kingdom.
Answer: Single cell, microscopic organisms, EUkaryotic cells
◍ Evidence supporting RNA as primary role in evolution of life.
Answer: - Some RNA molecules are catalytic- RNA catalyzes peptide bond
formation during protein synthesis- ATP (energy currency of cell) is a
ribonucleotide- RNA can regulate gene expression
◍ Bacteria.
Answer: Can be pathogens (Black Plague)Human biomeBreak down dead
animal and plant cellsUsed to make bread cheese antibiotics vitamins and
enzymes
◍ Bacteria are abundant where.
Answer: Extreme sites of temperature PH and salinity. Major part of human
microbiome
◍ Domain Archaea.
Answer: One of the three domains of life; contains prokaryotic cells that
often live in extreme habitats and have unique genetic, biochemical, and
physiological characteristics; its members are sometimes referred to as
archaea.
◍ False.
Answer: True or False: Fungi is a protist
◍ Domain Eukarya.
Answer: Domain of all organisms whose cells have nuclei, including
, protists, plants, fungi, and animals
◍ Major types of protists.
Answer: algae, protozoa, slime molds, water molds
◍ Protein.
Answer: What does RNA convert information stored in DNA into?
◍ Woese.
Answer: Who began the ribosomal RNA studies that led to the division of
prokaryotic organisms into the Bacteria and the Archaea?
◍ Eukaryotes (Fungi).
Answer: A nonmotile organism composed of long threadlike structures
formed from nucleated cells that is not-photosynthetic and absorbs its
nutrients is likely classified among ________________.
◍ Fluorescence Microscope.
Answer: A microscope that exposes specimens to ultraviolet, violet or blue
light and forms an image with the light emitted as a different wavelength
